There is no need to worry, your hedge will be fine. In your zone this Euonymus is not always evergreen, so it is losing it's leaves just like the deciduous trees do. It will all grow back in the springtime.
Some of the other Euonymus varieties WILL stay evergreen, and there are lots of them to choose from. I think you have a very handsome hedge there to be proud of!
